99-06 Silverado/sierra 5.3 and 6.0 complete    Pisc 1 (self-contained and oiled, no need to tap into vehicles oil at all!) intercooled kit with gauges, gauge pillar, all piping and belts required everything required for installation. Have belt for the 6.0 and 5.3 and everything needed!!! I have 45 pound fuel injectors, high-performance fuel pump, gauge cluster for pillar and more(Truck will need to be tuned or order tune from ProCharger afterwards) over 6K into this kit, I had it on an avalanche to help tow trailer for 103,000 miles completely trouble-free, and added tons of power to the truck and made towing and ease!!! then I was going to buy new truck and asked Pro Charger if there's anything they can do preventative before it goes on another truck. They said they can make it brand-new by refurbish and I sent it to them and paid $1500 to replace all all parts and seals on unit before I put it on my Silverado 6.0 I was going to buy for a heavier trailer. While unit was being revamped i was talked into a Duramax Diesel rather than the 6.0 so have no use for it. Amazing kit ads tons of power, Plus extremely reliable to drive as your daily driver with the added power.
